What are the main components of a wire-cut EDM machine?

The composition of the wire EDM machine tool: the bed, the wire mechanism, the taper cutting device, the coordinate table, the pulse power supply, the working fluid circulation system, the numerical control device and other parts.

The basic principle of wire EDM: use a moving thin metal wire (copper wire or molybdenum wire) as a tool electrode (connected to the negative electrode of the high-frequency pulse power supply), and pulse spark discharge on the workpiece (connected to the positive electrode of the high-frequency pulse power supply) , Cutting and forming.
